    1. MSc in Industrial Computing Systems Computer Communications Lecture 1. Lecturer: Dr. David Al-Dabass Room: N315 Tel.: 6015 email: david.al-dabass@doc.ntu.ac.uk

    3. Section 1: Introduction 1.1 Scope: Concerned with: Transfer of computer-based data over long distances.

    4. Cost & sophistication of Computers Communication Networks Ever more powerful computers at less cost enable Ever more powerful computers

    5. 1.2 Information channel capacity and bandwidth.

    6. A square wave can be thought of having a fundamental frequency plus harmonics

    7. The minimum bandwidth for a square wave to be still recognisable as a square wave is = 2 x freq.of sq. wave.
